The influence of the replacement of Sr by Ca on structural and luminescence properties of Eu2+-doped Sr2Si5N8 is reported. The Rietveld refinement of the powder X-ray diffraction data shows that the Ca2+ ion preferentially occupies the larger Sr site

Het is al circa 40 jaar bekend dat waterstof uit water geproduceerd kan worden met behulp van een fotokatalytische reactie. In 1967 ontdekte Akira Fujishima [1] dit effect namelijk bij titaniumdioxide.Sindsdien is er veel onderzoek verricht in dit va

The influence of the crystal structure of TiO2 on the photocatalytic activity was investigated. Methylene blue decolourization was used as a test reaction to give an indication of the number of excited electron-hole pairs available for photocatalytic

Fossiele brandstoffen raken langzamerhand uitgeput, komen uit politiek instabiele regio 's en zijn mede-veroorzaker van het broeikaseffect. We ontkomen er dus niet aan over te schakelen op duurzame energie-bronnen, zoals biomassa, zonne- en windenerg
